7 Claims.

The invention aims primarily to provide a novel and advantageous attachment for any of various kinds of chairs, which will form a comfortable leg rest when in one position, and will constitute a convenient table over the chair seat when in another position, the invention being, therefore, well adapted to fulfill the needs of persons who, from desire or necessity, sit a great deal.

Further objects are to make novel provisiony for attaching the device to a chair; to provide easily operable means for holding relatively movable parts of the device in proper relation with each other whether the attachment be serving as a leg rest or a table, and to provide for removing slack'from the leg-supporting web.

Figure 2 is a top plan View partly in section.

Figure 3 is aside elevation partly in section showing the device in use as a table over the chair seat.

Figure 5 is a detail vertical section on line 5-5 of Fig. 4. l

Figure 6 is a fragmentary disassembled perspective view showing one of the adjustable pivotal connections between sections of the device.

Figure 7 is an enlarged vdetail section on line 'I 'I of Fig. 1. ,l

Figure 8 is a fragmentary perspective view showing an attaching plate which may be provided to facilitate connection of the device with chairs other than the type shown in Figs. 1, 2 and 3.

Preferred details have been illustrated in the drawings and will be rather specifically described, with the understanding, however, that within the scope of the invention as'claimed, variations maybe made.

A portion of a chair I is shown, having a suitable seat I I and a transverse bar I2 at the front end of said seat. This bar I 2 is formed with two openings or sockets I3 and is provided with two downwardly projecting lugs I4 near said openings or sockets, thus adapting the chair fory connection of the combined leg rest and table, now to be described.

'I'he attachment includes Aa rectangular frame I which comprises an inner or rear short section,

I6, a somewhat longer intermediate section I1, and a still longer outer or front section I8, the three sections being hingedly connected by hinges I9 which are constructed to permit movement of said sections into different relations with eachV `V other, and locking of said sections against undesired relative movements when adjusted.

The inner section I6 includes two short side bars 20 connected by a transverse bar 2| which is preferably secured to said side bars 20 by means of screws 22. 'Ihe inner ends of the bars 20 are arched at 23 and provided with downwardly projecting fingers 24 receivable in the openings or sockets I3. The inner ends of the bars 20 are also provided with'two downwardly projecting lugs 25 to occupy positions at the front sides of the two lugs I4, and adjusting screws 26 are threaded rearwardly through said lugs 25 to abut the front sides of said lugs I4. yThe lower end of each lug 25 carries a pivoted latch 21 which may be swung from the released downwardly projecting position of Figs. 1 and 4 to the operative position of Fig. 3, in which latter position, the bill 28 of said latch 21 hooks behind the lug I4. The screw 26 is loosened somewhat before the latch is swung to this operative position, and when the screw is then tightened, said latch will be eiectively held in latching engagement with the lugy I4. It is preferable to secure a ilat spring 29 to the lug 25, said spring being cooperable at surfaces on with the pivoted end of the latch2'l to yieldably hold it in either of'v the positions shown. e

The intermediate section I1 of the frame I5 comprises side bars 30 connected by transverse bars 3 I, and the outer or front section L5 includes side bars 32 and an outer end bar 33.V The bar 33 is provided with reduced extensions 34 on its ends which extend through slots 35 in the inner sides of the bars 32, thelatter being tubular. Caps 36 close the outer ends of these bars 32, and screws 3l pass rotatably through these caps and are threaded through the ends 34 of the bar 33. By turning the screws 3l, the bar 33 may obviously be adjusted with respect to the inner end bar 2I. It will also be seen that both of these bars 33 and 2| may be detached when desired. This is of advantage in order that they may be inserted through hems 38 on the ends of a legsupporting web 39, and in order that a new web may be supplied whenever necessary. This web fmay` well be formed of canvas or the like, and

ever, the plate or table top 32 will form an ef- Each of the hinges i9 preferably comprises two toothed knuckles 4|, a screw 42 for clamping said knuckles together, and spring washer 43 interposed between the head of said screw and the adjacent knuckle, as seen in Fig. 6. This construction permits tight ,locking of the hinged joints between the sections of the device when said sec tions are in either 'leg-supporting position or table-forming position. By loosening the various screws 42 suiciently, the sections may be swung When the various sections are extended for legis not necessary that the latches 2l be engaged When the attachment is to` be connected with l Y a chair having a front seat bar of approximately theA type shown at 44!` in Fig. 8, an angular plate 45, may besecured to said bar, said plate having -j one opening 46 to receive ,the finger 24 and another opening 41 to receive the latch 2l. VThe bar is of course recessed in communication with the openings 46 and 41 and two of the plates 45 are of course used. f Y i From the foregoing taken in connection with the accompanying drawings, it will be seen that novel andV advantageous structure has been provided for carrying out the objects of the invention, and while preferences have been disclosed.

attention is again invited to the. possiblity of making variations within the scopel of the in:-

ve'ntion as claimed.

Iclaim:

and formed with an upwardly open socket,V said barhaving a downwardly projecting lug near said socket, and an attachment having a finger hooke I into said socket, said attachment having a second downwardly projecting lug; at the front side of and in contact with the rst mentioned lug.

2. A chair having a bar at the front of its seat and formed with an upwardlyopen socket, said bar having a downwardly projecting lug near said socket,V an attachment having a finger hooked into. said socket, said attachment having a second downwardly projecting lug at the front` sideA of the iirst mentioned lug, and a latch pivoted to the lower end of said second mentioned lug and swingable rearwardly into latching engagement with the. lower end of said rst lug.

g with respect to each other and the teeth of the knuckles will be heldV temporarilyken'gaged vby means of the pressure'exerted by the spring washers 43, until said Vscrews are again tightened.

` supporting purposes asV shown in Figs. 1 and 2,' it l 3.

In a leg rest, a frame having tubular side bars and a fixed cross bar at one end of said side bars, a second cross bar at the other ends of said side bars, thelinner sides of said., side `gbars having longitudinal slots through which the ends of VVsaid second bar extend, caps abutting and closing said other ends of said side bars, and adjusting screws extending rotatably through said caps and threaded through said ends of said second bar, saidscrews havingheads abutting the outer sides of said caps.

5. In an attachment for a chair having a, seat with a front member provided with sockets, a frame having downwardly projecting' fingers to hook into said sockets, said frame also having downwardly projecting lugs in advance of saidv fingers to occupy positions at the front side of the front member ofthe chair seat, and pivoted latches onsaid lugs Vfor engagement with the Y front member of the chair seat.

In an attachment for a chair having a seat with a front member provided with sockets a combined table and leg rest frame com-posed of inner, intermediate andfouter sections hingedly connected for movement from a longitudinally alined position to relatively angledV positions, said inner section having downwardly projecting fingers to hook into the sockets of the front. mem- 5 ber of the chair seat and alsoVV having downwardly projecting lugs inadvance ofv said ngers to occupy positions at the front side'of the front member of the chair seat and to contact with' the same to support said inner section in a substan,

tially horizontal position, pivoted latches on said lugs to engage, said frontmember ofthe chair seat to retain` said ngers in said sockets of said front member, and means for locking the. hinge connections. between said three sections ofr the frame, whereby when the intermediate section ispositioned vertically and the outer section is Dositioned horizontally, the latter may serveV as a tabletop.
